Review: Take it from a skeptic: After 3.5 years, no regrets! This Coway air purifier is perfect! - We purchased this unit in June 2022, nearly 3.5 years ago. That said, this review is coming from a place of experience with this air purifier. We had just adopted two cats that were born in the bushes outside our home, and I don't particularly care for cats (or more specifically, the smell of cats)! I was concerned about the price of this machine, not because it was crazy expensive compared to other machines that claim to be able to do what this purifier does, but because I didn't want to spend even half of what this thing cost just to keep the house from smelling like cats. On top of that, I didn't want to have to keep buying filters for it. I chose to bite the bullet and purchase this because I figured that if this device could keep the cat smell to a minimum, it would be worth every penny. The recommendation is every year or two, but they are so easy to clean that we were able to extend the filter life quite a bit! The outermost screen filters are quick and easy to get the dust off. It takes about one minute per filter (one on each side) to vacuum off. We clean these filters every 45-60 days. The innermost filters - the big ones with the charcoal - we clean every 12 months. Those take a little longer to clean, but no more than 5 minutes with a vacuum attachment. Everything on this device is easy to remove and replace. Now for the important part... Until just this very week, I have never - and I do mean NEVER - noticed a cat smell in our home. My in-laws have a cat, and they have commented several times over the years how amazing it is that our home never smells like cats - or any odors for that matter! My sister-in-law is allergic to cats but doesn't have any issues at our house. Fast forward to today, I have grown a bit fonder of the cats but still don't like cat smells! I came to desertcart today to purchase my very first set of replacement filters, if that tells you anything about the longevity of these filters! I decided to leave this review just in case anyone else is on the fence about this air purifier. It works. Perfectly. All day. Every day. Additionally, I no longer use expensive HEPA filters in our HVAC system because this purifier takes nearly everything out of the air that those would catch anyway. For anyone who's curious: We have a 1900SF home. I was able to find a great location for this fairly close to the middle of our home so that it purifies the entire house. I go weeks at a time without even realizing this thing is in the room - it just blends in and disappears! If it detects odors, it will speed up for a brief period of time, but almost always runs at the lowest speed - nearly silent. I'm certain that this would even work in larger homes than ours, because in our home it typically only runs at 25%. There are a number of controls so you can adjust the speed, setting, schedule, etc., but we never use them. We just set it and forget it. The power this unit can produce (and the amount of air it can move) is incredible. This purifier brings air in from the sides of the unit and exhausts it out from the top, creating perfect circulation. As an added (undocumented, unsupported) function, anything you place near the top of this unit (potpourri, air diffusers, essential oils, etc.) is quickly dispersed throughout the home.
Review: 5 yrs strong!! - I’m going on my 5th year using this device daily, it has rarely ever been turned off. I run it on the setting below the highest, always. I will say it isn’t quiet but it isn’t loud. It creates a nice white noise that is adaptable. I have replaced the filters in it every 9-12 months due to a dust issue living near a lot of farm land, plus I have all hardwood floors, no carpet. I have a small dog in the home who often has company and Im a smoker. Over all I feel like the air is fresh and it helps immensely with dust and dog hair! I never smell my dog or cigarettes in the home. When I come in after work and the house has been closed up all day, I can smell my plugins right outside the front door which is a great thing. I clean the pre-filters weekly and they normally have a good coating of dust and dander that I spray away down the sink. In the summer I sometimes find mosquitoes on the pre-filter! I hit the main filters with the Dyson about once a month as the fine dust does collect and prevent air flow. I have to admit that the original filters did a better job and lasted longer than the off-brand ones that I purchase for about $25 per set but the savings outweigh the loss of quality by far as they are quite comparable with fit and filtration. The sensor is very sensitive to the environmental changes and air flow will increase with change. I love that the front and back are also detachable by sliding upwards and can also be easily removed to be cleaned like the 2 magnetic sides that cover the filters. It has a night mode and a timer feature although I rarely use either. My home is a 1300 sq ft ranch style therefore the layout is somewhat boxy. The device is centrally placed however I believe the lay out of my home would be most benefited from an additional unit as the bedrooms still collect quite a bit of dust but are somewhat partitioned except the doorways. I will definitely purchase another Conway product when my budget allows as I’m very pleased with the reliability and ease of the airmega 400 however it was considered an investment at its price point.

## Questions & Answers

**Q: Does the area (1256 sqft) need to be one open area or can be split into multiple rooms with doors open ?**
A: Well first off no real air purifier expert would tell you to use the 1256 sq.ft. You want a minimum of 5 air changes per hour (ACH) and 1256 only provides about 2. If you are truly looking for the benefits of air purification then you should be looking at 500-700 sq.ft and no more. With that said, you lose efficiency if it has to go to multiple rooms and thus less ACH. Unless you have an industrial Air purifier built into your HVAC system at your house you should think about limiting one air purifier per room (with the appropriate amount of power to handle it).

**Q: I'm getting a shipping error for California. Why is there a restriction to ship to California? It doesn't go over the dimension or weight max.**
A: California bans electrostatic air filters because they produce unsafe amounts of ozone. Ozone damages your lungs. This also might be an Amazon problem, where they take reviews for similar products and stick them all together. I'm not sure the  Airmega 400 has an electrostatic system in it. I don't see the no shipping alert on its Amazon listing (I live in California) but I see it on Healthmate HM-400 listing.  The Wirecutter did a whole article and missed the electrostatic filter, so thanks CA. Electrostatic filters are very effective at removing particles but they produce ozone. If you're tired of smelling chicken poop, moving from a chicken ranch to an oil refinery would work, but.....

**Q: Does this work well to remove pet odors? It is so hard to hard to find any straight forward answers about odor removal on any of these higher end unit**
A: I love it.  I have a very sensitive nose and breathing. Works great for pet odors!  I need one for the other side of the house.  Worth the investment.  I've tried some of the other $200-$300 purifiers

**Q: Will this work for oil painters - i need it to help with the removal of vocs such as turpentine and mineral spirits?**
A: NOT good at all. I wish I could say otherwise since I own this product. I have 3 different instruments that measure VOCs. DO NOT depend on this product for VOC removal. I bought the Conway and the VOC testing instruments because I am a victim of VOC poisoning in my living space.  After zeroing the testing instruments and getting baseline VOC measurements, the Conway did nothing to reduce them - even at the highest fan setting after 24 hours. I still love the Conway though as it does a SPECTACULAR job at reducing a full range of microparticulate matter.
